INCINERATOR FOR GARBAGE, EXCREMENT, 850.

To all whom it may concern:

Be it known that I, ALFRED L. SCHELL- HAMMER, a citizen of the UnitedStates, residing at Varren, in the county of "Warren and State ofPennsylvania, have invented certain new and useful Improvements inlncinerators for Garbage, Excrement, &c.; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to incinerators for garbage, excrement, andhospital and other.

waste.

The objects of my present invention are: first, to provide for the quickand eifective evaporation and consumption of urine or other liquids andthe desiccation and burning of solid excrement or other deposits in anodorless manner; second, to provide means for disposing of urine orother liquids separate from solid excrement or other solid matter;third, the provision of a urine or liquid receptacle so related to thereceptacle for solid matter that any liquid, especially urine, which isfrom necessity or otherwise deposited in the receptacle for solidmatter, may overflow into the urine or liquid receptable; fourth, to soconstruct the receptacle for solid matter that foaming, heated orboiling liquids therein will enter the urine or liquid receptacle beforereaching the highest point of the receptacle for solid matter; fifth,the provision of an incinerator possessing the qualities mentioned andother advantageous qualities, which is not only simple and inexpensive,but which can be constructed for permanent use or made in portable formto meet all requirements.

With the above andother objects in view, the invention consists in therelative operative arrangement of devices or parts and in theconstruction, arrangement and com bination of elements to be hereinafterdescribed and particularly pointed out in the subjoined claims.

In the drawings, consisting of two sheets,-Figures 1 and 2 are centralvertical sections of the complete incinerator taken at right angles,respectively. Fig. 3 is a plan view of the same. Fig. 4 is a horizontalsection taken on line 4.t, Fig. 1.

Specification of Letters Patent.

Application filed August 27, 1910.

Patented A11 11, 1914. Serial No. 579,286.

Fig. 5 is a horizontal sect-ion taken on line 5-5, Fig. 1. Fig. 6 is avertical section taken on line 66, Fig. 1, the kettle being removed.Fig. 7 is a vertical section taken on line 7-7, Fig. 1.

Referring now to the drawings in detail, like letters of reference referto like parts in the several figures.

It is essential that the incinerator be made gas-tight to prevent theescape of odors and the gases of combustion and it may therefore be madeof any suitable material meeting this requirement. I have, however,shown the casing, designated A, made of sheet and cast metal andprovided at its lower end with an ash-pit B, the casing at this pointbeing equipped with a door 5 for the convenient removal of ashes.

Supported within the lower portion of the casing, but above the ash-pit,is a firepot C provided with grate-bars c of any approved form, accessto which may be had in any suitable manner.

In preferred form I construct the intermediate portion of the casing ofcast metal, as at D, and above and below the cast metal, sheet metal ispreferably used, as at (Z, d respectively. While this is now thought tobe most desirable, it is not necessary that such construction be adheredto.

The cast metal intermediate portion of the casing is part of an endlesstrough D supported by, and if desired secured to the upper end of thesheet metal lower portion (Z of the casing; the upper sheet metalportion (5 of the casing surmounting the cast metal trough-likeintermediate portion. The casing is preferably of oval formation, butthis is only a matter of choice or convenience, as will presentlyappear. The casing is provided with a removable top E, having in thisinstance two holes a, so that two persons can be accommodated at thesame time, and for this reason, the casing is made of oval formation, asthe oval shape occupies less floor space while permitting the use of twoholes in the top. For a single seat top, a cylindrical casing is moresuitable, and when more than two seats are desired, the casing iselongated accordingly. As the top is preferably made of iron, I securethereto wooden fiber, or other closet seats F, more suitable for contactwith the skin of a person than iron, and hinged to these seats arecovers F which prevent the escape of odors or gases from the casingthrough the holes 6 and those of the seats registering therewith.

The cast metal endless trough D forms an endless urine or liquidreceptacle G which surrounds a kettle or receptacle H pivotally mountedin the inner wall of the urine or liquid receptacle and situateddirectly over the fire-pot C and beneath the openings 6 in the top E;said kettle or receptacle H being adapted to receive the solid matter.

Owing to the endless trough D being utilized as a urine or liquidreceptacle, the incinerator is greatly simplified in construction; andas said receptacle and the kettle are in the same horizontal plane withthe fire-pot'beneath, the receptacle and kettle are subjected tosubstantially the same degree of heat. By means of this arrangement, avery compact incinerator is produced with maximum capacity for fluidmatter. Connecting the inner and outer walls g, 9 respectively, of saidreceptacle is a flue I forming an opening for supplying the fire-potwith fuel, the opening being closed by a door '5. The opening ispreferably formed in one of the long curved walls of the casing so as tomore easily admit the fuel.

The kettle or receptacle has trunnions h,

' M, at diametrically opposite points which I trunnion h being journaledin a pocket H formed on the urine or liquid receptacle. This arrangementpermits of easily'removing the kettle or receptacle H from the easingafter having removed the top E therefrom. By providing the kettle orreceptacle H with trunnions, as specified, it can be easily turned todump the contents onto the fire in the fire-pot beneath, but it isnecessary that one of said trunnions be extended directly, or by meansof a cooperating part, through the casing so that a wrench or crank canbe applied thereto. In this instance I have shown a rod J which has apocket j at one end into which the square extremity of the trunnion hfits and at its other end is itself made square, as at f, so that thedesired implement may be applied for manipulating the kettle orreceptacle H.

At one side and at the upper end of the casing is a combined draft andsmoke-box K, from which rises a smoke-pipe 7c adapted to provide thenecessary draft. Since the outer wall of the urine or liquid receptacleforms the intermediate portion of the casing A and said receptaclesurrounds the kettle or receptacle H, it follows that there is a space Lbetween said kettle or recepta- 01c and the top E of the casing, andthis space is in communication with the combined draft and smoke boxthrough an opening Z in the upper portion of the casing. The said box isalso in communication with the space below the kettle or receptaclethrough a passage M created by a tube M connecting the inner Wall 9 withthe outer wall of the urine or liquid receptacle and in a plane betweensaid passage and the opening Z a horizontal wall M is provided in thecombined draft and smoke-box, which wall divides the said box into twoparts or chambers N, N said parts being connected by a passage 02.

In the upper wall of the combined draft and smoke-box is an air-inlet 0adapted at certain times in the operation of the apparatus to be closedby a damper 1? located in the upper chamber N. Said damper comprises aclosure-plate p hinged to the underside of the upper wall of the saidbox as at 29 and a deflector-plate p hinged to the free end of saidclosure-plate, the point of its connection to said closure-plate beingnearer one end than the other so that it will hang unbalanced from saidclosure-plate when the latter assumes a position between those shown indotted lines and in full lines, Fig. l. The damper is manipulated by arod-p pivoted or otherwise secured to the closure plate 10, and itextends from side wall to side wall of the combined draft and smoke boxso as to completely shut ofi direct communication between the space Nabove the kettle or receptacle H and the smoke pipe, but when the damperis closed for this purpose, indirect communication is had through adraft flue Q, which connects the space N with the ash-pit B, through thefire-pot O and tube M in the urine or liquid receptacle, and finallythrough the draft and smoke-box to the smoke stack.

Then raising the damper P to a certain point, the inner end of thedeflector-plate p comes in contact with a lip R on the upper wall towhich the damper is hinged, and slightly opens the damper, at the sametime restricting the passage between the closure plate and the air-inlet,O, and as the closure plate is raised farther, said passage is restricted in proportion to the extent the 'deflector-plate is raised, andwhen the air-inlet O is closed by the closure-plate, the deflector-platehas reached the limit of its opening movement, as clearly shown indotbaffle-plate and the parts of the kettle surrounded by said plate arecompelled to travel to the left in Fig. 1, under said plate and thenceto the right above said plate, through the flue M and into the combineddraft and smoke-box K, and from the latter out the smoke-pipe.

At one side of the longitudinal center of the urine or liquidreceptacle, the inner wall 9 thereof has an inwardly-directed flange T,against the underside of which the corre sponding portion of the upperedge of the kettle or receptacle H bears, and at the opposite side ofsaid center, the upper edge of said kettle or receptacle has anoutstanding flange T which bears against the upper corresponding edgeportion of the urine or liquid receptacle. This arrangement permits thefree dumping of said pot or receptacle while prevent-ingthe escape ofthe hot gases into the space L above said pot or receptacle.

As hereinbefore remarked, urine and other liquids may of necessity bedeposited in the kettle or receptacle H and when boiled, es-

r pecially urine, will flow over the edge of the same. As this ispreferably to be avoided, I have cut-away or notched a portion of theinner wall of the urine receptacle and correspondingly notched thekettle or receptacle H, as at t, and as the outstanding flange T iscontinued around the notched portion of said kettle or receptacle, theliquids may overflow into the urine or liquid receptacle before it isfound necessary to incinerate the matter in the apparatus, and if theliquid in the kettle or receptacle does not overflow be foreincineration or when incineration is commenced, it will overflow at thenotched portion of the kettle or receptacle into the urine or liquidreceptacle when boiling. The urine or liquid receptacle G as well as thekettle or receptacle H, is subjected to the heat of the ascending gasesfrom the fire-pot and complete incineration of liquid and solid matterthus assured.

Instead of entirely consuming the matter in the pot or receptacle H, itcan, when thoroughly dried, be dumped into the fire-pot and used asfuel.

Arranged outside of the incinerator casing is a urinal or liquidreceiving vessel U into which the urine or other liquid is initiallydeposited and from it conducted through a pipe u to the urine or liquidreceptacle G. The pipe u is connected to the bot-tom of said urinal orliquid receiving vessel so as to entirely drain the same. The upper endof the urinal or liquid receiving vessel U may terminate in any desiredhorizontal plane most convenient for the purpose for which itmay be usedand it has its upper end closed by a lid or cover 10 Surrounding theincinerator jacket is a jacket V separated from said casing by anintervening air-space W, said jacket extending from the top of theincinerator to within a short distance from the bottom. The airspace W'is open at the bottom and closed at the top and at certain times is incommunication with the combined draft and smoke box through the airinlet 0 therein. The air enters said air-space at the bottom and risesto the top, it being heated by contact with the incinerator casing. henthe damper P is in the position shown in Fig. l, the heated air entersthe combined draft and smoke box through the air-inlet O, passing overthe top of the pot or receptacle H and the urine or liquid receptacle G,carrying with it the odors and gases from both, which pass with the airthrough the draft tube Q into the ash-pit B and from the latter into theflre to be there consumed, the products of combustion being carried outthe smoke-pipe, as previously described.

When the damper is opened, as shown in dotted lines, the odors and gasesfrom the material in the incinerator are carried out directly throughthe smoke-pipe without passing through the flre.

Certain features of the incinerator herein illustrated and described areshown and claimed in my co-pending application filed July 25, 1910,Serial No. 573,627, these features being the jacket V separated from thecasing by an intervening air-space, the combined draft and smoke box Ksurrounded by said air-space and being at certain times in communicationtherewith, the damper P controlling such communication, and the draftflue Q which connects the space N above the kettle H with the ash-pit B.Also the broad idea of the fire chamber (which the firepot C forms partof) serving to form part of the wall of the liquid receptacle G.

Having thus described my invention, what I claim is,

1. An incinerator comprising a casing having a fire-pot, a kettle withinsaid casing in operative relation to said fire-pot, a liquid receptaclein the horizontal plane of said kettle and also in operative relation tosaid fire-pot, said liquid receptacle being arranged to receive theoverflow from said kettle, and a liquid-receiving vessel connected withsaid liquid receptacle.
